Phantasm enchantment for spears

The new spear is a very interesting addition to the game, and a tiered weapon could come with new or repurposed enchantments such as breach & looting. However, one new enchantment that could change its reputation could be a unique one like riptide: Phantasm (1-3).

Dealing an unmounted crit or successful charge with the Spear (and possibly trident) could create a spear underneath them, which pops up a second after the initial summon indicated with a mark below, and each level increases the spear count by 1 block in each direction, all at the cost of increased fatigue speed for charging and thus encouraging more pinpoint timing. Dismounting mobs that somehow survive would become evermore satisfying and allow for better crowd control in raids, zombie sieges in villages, or in a violent Piglin bastion situation.
